主权项

1. A fixation robot enabling the alignment of fractured bones in orthopaedic operations comprising:
a fixed retainer jaw connected to one piece of said fractured bone; a moving retainer jaw connected to the other piece of said fractured bone; and a motion transfer assembly providing motion to said moving retainer jaw; and characterized in that said motion transfer assembly comprises the following:
a Y-plane advancer parallel to the ground;an X-plane advancer at an angle of 90° with respect to the Y-plane advancer and moving linearly on the Y-plane advancer;a Z-plane advancer moving vertically with respect to the ground and moving linearly on the X-plane advancer;a moving column carrying the moving retainer jaw and moving linearly on the Z-plane advancer; anda cardan shaft associated with the moving retainer jaw and providing rotational movement to the moving retainer jaw around the x, y and z axes by being driven plurality of motors and reducers from different directions.
